They are widely used to secure furniture parts in tables and chairs. They are often used to fix wood and metal structures together as these bolts are usually flat on one end and pointed on the other, with the part designed with closer threads meant to go into metal. Hanger bolts have threads on both ends, and such a double-ended design makes such bolts suitable for use in furniture buildings. The unthreaded cylindrical section in the middle of the shaft allows them to act as pivot points, enabling the rotation of other attached parts. These bolts are essential for putting together moving parts like pulleys and gears. For companies dealing with machinery or maintenance work, products like the shoulder bolt are extremely useful.
